Cl. G09b 7/00, 3/00 US. CI. 35-48 6 Claims ABSTRACT OF THE DISCLOSURE A system for comparing an answer input to the system by a respondent with a programmed answer already present in the system, with regard to a variety of criteria. A memory device retains a predetermined answer or set of answers, to a problem, represented by a plurality of digits. The respondent, by means of an input device, submits his answer to the system. Comparator and other circuitry compares the respondents answer with the present correct answer and, by means of other circuitry, displays: (1) the absolute value of the deviation of respondents answer from the correct answer; (2) the number of digits of the correct answer which appear in the respondents answer; (3) the number of pairs of digits of the respondents answer and the preset correct anwser, which appear in the same order as they do in the preset correct answer.

This application is a substitute for abandoned application Ser. No. 416,743, filed Mar. 17, 1954.

This invention relates 0 devices for comparisons between the preset correct answer to a problem, and the attempted selection of such a correct answer by signalling means for human responses.

Means are well known in the art permanently to record a response by inactivating the signalling means of all competit'ors or subjects by a signal from any subject, as disclosed in Patent No. 1,153,737, issued to Van der Hoorn et al. on Sept. 14, 1915; or for such inactivation by the response of any subject corresponding to a preset correct answer comprising a single item, as disclosed in Patent No. 2,562,179, issued to Dorf on July 31, 1951. Also, means are well known in the art permanently to record a correct response by erasing the indications of the responses of all losing subjects, when the irrevocable selections comprising the response of a Winning subject exactly correspond to all of the plurality of items of a preset correct answer, such items selectable in any order irrespective of sequenpe, as disclosed in Patent No. 2,654,163, issued to Reynolds on Oct. 6, 1953.

The present invention has for a principal object the provision of a multi-purpose system for continuous analysis of the accuracy of data in at least one human response which comprises the attempted selection of the plurality of correct items comprising the correct answerto a selected problem-particularly a correct answer comprising such correct items in a desired sequence, or a multiple choice of any combination of such items, or selection of items to approximate a desired numerical-total. The system further contemplates continuous analysis among a plurality of such responses, as from a plurality of local or remote stations, or combined groups of stations, the output of such analysis repetitively to determine and to indicate at least one leading and nearest correct response, its degree of accuracy, and its respective margin of leadership over its closest competitors, for whom similar indications are provided. It is the further object of many of such preset correct answers comprising sequential or numerical-total items, to test the ability of the subject to recall data such as words, as contrasted with his recognition of data comprising multiple choice items; selectively with provision that each subject may erase his response.

For the purpose of accomplishing the desired objects this invention involves a number of novel features.

This invention features its sequential, multiple choice, and numerical-total types of response functions, and its selectivity among them. It features means to determine the three alternative conditions of each item in each response, correct, incorrect, or unanswered. Features of the invention economize upon the necessary means: thus to require only one bit (binary digit) of preset information common to all channels and groups in thesystem, for each preset correct item; to require only one bit of information and associated means for each response item whether correct, incorrect, or unanswered; to use many of the same means for each of a plurality of channels, groups, and combinations, for each of a plurality of response functions, in each of a plurality of cycles, multiplecycles, and programs; and in a continuous plurality of comparisons, to economize in duplication of input control, signalling, and analyzer means, by recording each desired analyzer output by permanent recording means without its interference with any other means.

The system additionally features its continuous comparator indications with reference to individual station responses in each of a plurality of groups of stations, and also with reference to group combinations of station responses. Without interference with such continuous indications, the system additionally features means to record indications of such outputs at any time or interval, and similarly to record the time and chronological order of responses achieving preset standards of accuracy.

The system additionally features means to provide a predetermined relationship between inputs comprising station responses, and the corresponding outputs of the analyzers; despite, for example, signal variations caused by each such station remotely situated, such variations including the number of pulses.

Other features of the invention will be described and claimed hereinafter.

The objects and features of the system described in this specification may be clarified in terms of its uses in many expanding industries and services.

Human responses may comprise the answer or reaction of an individiual. designated as a contestant or subject, in response to a question or situation, designated as a problem. The examiner conducting the test or the analysis of comparative data, may desire selectively to segregate each subject intoseparate or overlapping groups of subjects. The examiners testing methods, and grouping of subjects, may be based upon the personal characteristics of each subject; thekind of problem confronting each subject; and any statistical, scientific, psychological, economic, entertainment, or other factors of which control is desired.

Industry and education, for office, shop, classroom, and military purpoes, need to analyze effectiveness of techniques for production, management, teaching, training, and personnel; to test intelligence and aptitudes for guidance in choice of education and career; and to examine human responses for purposes of competition, recognition of merit, progressive education, etc.

Military and scientific activities also need means to achieve similar results, for example, for each officially listed function of each branch of the Psychological Sciences Division, Ofiice of Naval Research. Functions of the Physiological-Psychology Branch include human engineering, physiological correlates of behavior, audition, vision, other special senses, and perception and spatial
